I'm definitely calling my doctor to set something up just to make sure. I'm 29 weeks pregnant and a while ago noticed that when I'm up doing things for a long period of time a little above my belly button will start to hurt to the point where it won't stop until I go to lay down which sucks if I'm out doing something. When that happens if I talk too loud or cough or use those muscles in general it just hurts. When I was laying down and went to get up I noticed a little bit of a bump that only popped up like that when I sat up from laying down. I'm just kind of worried that's what it is but I'm not sure because I've never had one before, I was just hoping someone could tell me if that's what it sounds like or if you've had something similar happen.
